What is a cricket on a roof?

A cricket on a roof is a colloquial term used to describe the small metal flashing piece that is installed on a roof to divert water away from areas where two surfaces meet, such as a chimney or a junction between two sloped surfaces. The purpose of a cricket is to prevent water from pooling and causing leaks or damage to the roof structure.

Cricket can be made of various materials, including metal, wood, or asphalt shingles, and are typically installed by professional roofers during the construction or repair of a roof. The shape and size of a cricket can vary depending on the specific needs of the roof and the surrounding structures.

In addition to preventing water damage, crickets can also help improve the overall aesthetic of a roof by creating a smooth transition between different roof surfaces. Properly installed crickets can also help improve the longevity and performance of a roof by reducing the chance of water infiltration and leaks.
